aruco linux

[lolmuele]

Can anybody explain how the i could get opentrack with aruco on linux.
I have only found one guide in the depths of the internet and it didn't work at all for me.
I can install opentrack, but have no idea how to add aruco although there are folders like aruco-tracker and aruco inside the opentrack folder.
i am running ubuntu 20.04 and am relatively new to linux (only had it for abt 8 months)

Build https://github.com/opentrack/aruco. Set SDK_ARUCO_LIBPATH.

[lolmuele]

where do i set the libpath ?

[sthalik]

cmake cache

[lolmuele]

I did this
//Aruco paper marker tracker static library path
SDK_ARUCO_LIBPATH:FILEPATH=/usr/local/lib/libaruco.a
but it still isnt there do i have to rebuild opentrack for it to appear ?

[sthalik]

Yes.

[lolmuele]

no, even rebuilding on entirely new source doesn't seem to work i have no ideas

[lolmuele]

i was just being stupid and used a temporary version of libaruco my system made it works now thx

The install target is broken. I should remove it completely. Point to the .a inside the build directory instead.

And done.
